Intra-cavity lesion positioner in capsule endoscopy

Abstract

The invention relates to an intra-cavity lesion positioner in capsule endoscopy. The intra-cavity lesion positioner comprises a capsule endoscope for detecting and discovering a lesion portion and is characterized by further comprising a capsule positioner, the capsule positioner is connected with the capsule endoscope through a remote control disconnecting and connecting device, the capsule positioner comprises a capsule shell, an automatic parking and positioning device, a positioning signal transmitter, a signal transmitter remote control switch and a battery, the automatic parking and positioning device is used for fixedly parking the capsule positioner on the lesion portion, the positioning signal transmitter is electrically connected with the battery and the signal transmitter remote control switch, and the signal transmitter remote control switch receives an instruction and controls the positioning signal transmitter to transmit positioning signals. The intra-cavity lesion positioner is ingenious in structure and convenient to operate, an intra-cavity minimal lesion can be accurately positioned in a laparoscopic minimally invasive operation is performed, operation efficiency is improved, positioning errors are avoided, operation errors are reduced, the capsule endoscope and the capsule positioner are mutually dragged, and tumbling of the capsule endoscope in an intestinal tube and examination blind areas are decreased.

Description

technical field [0001] The invention relates to a locator for locating intracavitary lesion parts during endoscopic examination, in particular to a locator for intracavity lesion during capsule endoscopic examination, which belongs to the technical field of medical equipment. Background technique [0002] With the continuous development of medical technology, minimally invasive surgery has been widely used in the medical field, which has the advantages of less trauma, less pain, and faster recovery. Lesion location is an important technical problem in minimally invasive laparoscopic gastrointestinal resection, especially for small gastrointestinal inner wall tumors. At present, the method of locating the lesion mainly relies on image data to judge. In the past, such image data was mainly obtained by colonoscopy, but it has disadvantages such as inconvenient operation and causing pain to patients. Therefore, medical workers have developed capsule endoscopy, and with the grad...

AI Technical Summary

Problems solved by technology

[0003] Although capsule endoscopy provides a feasible inspection solution for intestinal parts that could not be inspected in the past, capsule endoscopy cannot accurately locate the images taken along the way

That is to say, the presence of lesions can be found in patients undergoing capsule endoscopy. Doctors can only vaguely judge the general location of lesions based on case imaging and capsule working hours, and cannot accurately locate them.

However, accurate positioning is required for surgical resection of the lesion, which requires repeated touch positioning and verification after incision, which seriously reduces surgical efficiency and even causes large deviations during resection
